From: Arnd Bergmann <arnd@arndb.de>
As discussed previously, a lot of the older wifi drivers are likely
entirely unused, Though we can't know for sure.
As suggested by both Greg and Jakub, let's remove the ones that look
are most likely to have no users left and also get in the way of the
wext cleanup. If anyone is still using any of these, we can revert the
driver removal individually.
I would suggest merging these for net-next after 6.7-rc1 is out, to give
them the maximum amount of time for users to speak up before a release
comes out.
This kills off all pcmcia wifi drivers, and all wext users in
drivers/net/wireless, but not the ps3-gelic-wireless driver in
drivers/net/ethernet, or the staging drivers.
In staging, rtl8192u was already removed in the meantime, while rtl8712
and rtl8192e are apparently still used. I have not been able to find
out whether ks7010 is still in use.

With all the other PCMCIA WLAN adapters gone from the kernel, this is now
the last remaining device with this interface, but as far as I can tell,
all the actual libertas users were actually using either SDIO or USB.

From: Arnd Bergmann <arnd@arndb.de>
This is a wireless extensions style driver for 802.11b USB dongles,
with partial support for cfg80211 interfaces.
As these are all external dongles, there are probably few users that
have not yet replaced them with cheap 802.11n devices that work better.

From: Arnd Bergmann <arnd@arndb.de>
Planet WL3501 is another PCMCIA driver for pre-802.11b interfaces
(2Mbit/s) with incomplete CFG80211 support.
This was marked as orphaned in 2017 but has been unmaintained
for a long time before that.

- * Written originally for Linux 2.0.30 by Fox Chen, mhchen@golf.ccl.itri.org.tw
- * Ported to 2.2, 2.4 & 2.5 by Arnaldo Carvalho de Melo <acme@conectiva.com.br>
- * Wireless extensions in 2.4 by Gustavo Niemeyer <niemeyer@conectiva.com>
- *
- * References used by Fox Chen while writing the original driver for 2.0.30:

- * 2. Access Point Firmware Interface Specification for IEEE 802.11 SUTRO
- * 3. IEEE 802.11

- * 5. ISA card driver - wl24.c
- * 6. Linux PCMCIA skeleton driver - skeleton.c
- * 7. Linux PCMCIA 3c589 network driver - 3c589_cs.c
- *
- * Tested with WL2400 firmware 1.2, Linux 2.0.30, and pcmcia-cs-2.9.12
- * 1. Performance: about 165 Kbytes/sec in TCP/IP with Ad-Hoc mode.
- * rsh 192.168.1.3 "dd if=/dev/zero bs=1k count=1000" > /dev/null
- * (Specification 2M bits/sec. is about 250 Kbytes/sec., but we must deduct

- *
- * Tested with Planet AP in 2.4.17, 184 Kbytes/s in UDP in Infrastructure mode,
- * 173 Kbytes/s in TCP.
- *
- * Tested with Planet AP in 2.5.73-bk, 216 Kbytes/s in Infrastructure mode
- * with a SMP machine (dual pentium 100), using pktgen, 432 pps (pkt_size = 60)

Why net-next? I want to take these to wireless-next to avoid any
conflicts with other wireless patches.
We could take these to wireless-next after we submit the last new
features (-next) pull request to v6.7, so most likely already next week.
So if anyone has any problems with these speak up now.

My mistake, I actually rebased them on top of wireless-next before
sending out the patches, I just forgot update the text I had
already written a week earlier.

This patch didn't make it to the list, I guess it was too big. But it's
available from the pending branch:

I am inclined to remove this one as well, it's just so old.

Ah, good that we are on the same page then :)

Thanks for the patches! I applied them to our pending branch for some
build testing, there were few conflicts I guess due to recent cleanup
patches but obviously easy to fix :)

These have indeed been very common back in the day, I'm still using
a 2003-vintage 1.5 GHz Pentium-M 'Banias' Acer Travelmate 292LMi
notebook using ipw2200 (and have two spare ipw2200 mini-PCI cards).
Works still fine using v6.5.8-rc1 and WPA2PSK/ CCMP (sadly it does
not do WPA3) and I do use it semi-regularly (running the latest
stable- or stable-rc kernel of the day).
While it would be nice to replace it with an ath5k based card (to
get WPA3 support), the card isn't that easy to reach in the notebook,
so it would be sad to see this go.

While I'll cope if ipw2200 goes away (giving me the impetus to replace
the ipw2200 card with ath5k - or at least to use an ar5212/ar2414 ath5k
or bcm4306/2 b43 32 bit PCMCIA/ cardbus card (inconvenient, with the
antenna sticking out) until then), these have been so ubiquitous in
their days that there will be quite a few surviving specimens around
(and this one is actually still in semi-regular use with current
kernels/ userland, not daily, but 2-3+ times a month, mostly for
isolated firstboot configuration of various networking gear).

Wow, I'm very surprised that ipw2200 still works after 20 years. Thanks
for the report, I think it's best that we still keep the ipw2x00 driver
in the kernel.

Hi Arnd!
There is some non-x86 hardware like the Amiga that still uses PCMCIA-style networking
cards on machines like the A600 and A1200. So, unless these drivers are actually causing
problems, I would rather not see them go yet.
Thanks,
Adrian

Do you know of any systems other than the Amiga that are still
in use with new kernels and that rely on PCMCIA networking?
I know that Amiga has its own simple CONFIG_AMIGA_PCMCIA
implementation that is incompatible with CONFIG_PCMCIA device
drivers, so it is not affected by this.
For the few ARM systems that still support a CF card slot,
these tend to be used for IDE type storage cards because their
internal flash is too limited otherwise.
Arnd

There is a cost maintaining these drivers so I would like to see more
information in the report, at least:
* exact driver and hardware used
* last kernel version tested
* kernel log messages from a successful case
Here's a good example:

I manually applied these 9 to wireless-next:
4b478bf6bdd8 wifi: libertas: drop 16-bit PCMCIA support
77e49bec6414 wifi: atmel: remove wext style at76c50x drivers
6853c70ba5ed wifi: remove orphaned cisco/aironet driver
d0172d5f7576 wifi: remove obsolete hostap driver
757a46c2a7a9 wifi: remove orphaned zd1201 driver
1535d5962d79 wifi: remove orphaned orinoco driver
6b9dbaff83d6 wifi: remove orphaned ray_cs driver
238349207cd3 wifi: remove orphaned wl3501 driver
bec95598b24a wifi: remove orphaned rndis_wlan driver
I dropped this patch as we got several reports about people using the
driver:
[RFC] wifi: remove ipw2100/ipw2200 drivers
The patches are queued for v6.8. Arnd, thanks a lot for cleaning this
up!
